Be it known that 1,,J6zsnr Nest, a subieetpf h Ki q Hu eam re$ili1 e Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Motormel s Seats, of which the following is a specification.

The primary object of the invention is the provision of a seat especially adapted for motormen upon vehicles, the seat being readily adjusted for resiliently holding persons of different weights and heights.

A further object of the device is the provision of a seat in the form *of a stool, the height of which is readily adjustable while a cushioning device is included adapted for adjustment in accordance with the weight of the person using the seat.

A still further object of the invention is the provision of a vertically adjustable seat which possesses great strength and durability and is easily and inexpensively manufactured, the device also being capable of quick installation and requiring a minimum amount of floor space when set up for use.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is an elevational view of the device, portions being shown by dotted lines in an adjusted position and Fig. 2 is a vertical central sectional view taken through the device.

My seat or stool provides a comfortable support for a person wherever required and consists of a base 10 in the form of a post having an annular bottom flange 11 secured by means of holdfast devices such as screws 12 to a support such as the floor 13 of a street car platform. An upright shaft 14 is axially arranged through a threaded bore 15 of the post 10 and is secured within a socket 16 in the lower end of the bore by means of a transverse pin 17. A cup-shaped member 18 is threaded for vertical adjustment within the bore 15 having the shaft 14 freely extending through a central perforation 19 in the bottom 20 of the seat member. A roughened top flange 21 is provided upon the member 18 whereby the latter may be readily adjusted relative to the post 10, while a cushioning spring 22 encircles the shaft 14 and is arranged with its lower end portion positioned Within the cup-shaped member 18 and seated upon the bottom thereof. I a

A seat 23 of any "desired form Such as a circular V is arranged, with a collar 24 slidably positioned upon the shaft 14 mountst r th uppe endln the. sp ine22 a annulus 25 being secured to the bottom of the seat 23 and attached to the collar 24 by a plurality of legs 26.

An adjusting nut 27 is threaded upon the upper threaded portion of the shaft 14 be neath the head 28 of the shaft and bears against the collar 24 in juxtaposed relation to the spring 22. A boss 29 depends from the collar 24 within the spring 22 for giving a longer bearing to the shaft 14 projecting therethrough.

It will be understood that by lowering the nut 27 by turning the same upon the shaft 14 by means of a hand ring 80, the seat 23 will be lowered for convenience of a shorter person as illustrated by dotted lines in Fig. 1 of the drawing, while the spring 22 will be compressed. The compressing of the spring 22 just referred to renders the same more rigid so that it will be better positioned for supporting a heavier weight but if it is desired to maintain the normal tension upon the spring 22 when the seat 23 is lowered, the supporting cup-shaped member 18 may be moved downwardly by screwing the same to a lowered position within the bore 15 of the post 10. In a similar man ner, when it is desired to increase the tension upon the spring 22 for accommodating a greater weight upon the seat 28, the cupshaped member 18 is elevated by screwing the same outwardly of the bore 15, thereby further compressing the spring between the collar 24 and the bottom 20 of the cupshaped member.

It will be seen that a stool of great strength is thus arranged, the same being adjustable in height and rendered comfortable by means of the supporting spring 22, the tension of which may be readily adjusted corresponding to the weight of the user.

What I claim as new is 1. In combination with an upright postshaped base having a threaded bore, a shaft axially arranged within said bore fixedly secured to the base at the inner end of the bore and having a head at its upper end, a cup-shaped support threaded for Vertical adjustment within said here with a perfo ration through the bottom of said member through which the shaft freely extends, a

helical spring surrounding tl1e,sl 1aftseatedwithin the cupshaped member upon the bottom thereof, and a seat slidably positioned upon the shaft and mounted upon the upper end of the spring. 7

2. In combination with an upright postshaped base having a threaded bore, a shaft axially arranged Within said bore fixedly secured to the base at the inner end of the bore and having a head at its upper end, a cup-shaped support threaded for vertical adjustment Within said bore with a perforation through the bottom of said member 15 through which the shaft freely extends, a helical spring surrounding the shaft seated within the cup-shaped member upon the bottom thereof, a collar slidably arranged upon the shaft and positioned upon the up 20 per end of the spring, a seat supported by said collar and arranged above the head of the shaft, and an adjusting nut threaded upon the shaft and bearing against the upper side of said collar and a hand engaging 25 ring carried by said nut.

In testimony whereof I afiix my signature.
